Anti-smooth muscle antibodies are antibodies (immunoglobulins) formed against smooth muscle. These antibodies are typically associated with autoimmune hepatitis. [1] [2] These antibodies can be directed against actin, troponin, and tropomyosin. [3]
ACTA2 (actin alpha 2) is an actin protein with several aliases including alpha-actin, alpha-actin-2, aortic smooth muscle or alpha smooth muscle actin (α-SMA, SMactin, alpha-SM-actin, ASMA). Actins are a family of globular multi-functional proteins that form microfilaments .
In coeliac disease, anti-actin antibody levels correlate with the level of intestinal damage. [2] [3] In autoimmune hepatitis, anti-actin antibody levels correlate with patterns of immune recognition, [4] the pattern of recognition was specific to a small percentage of autoimmune hepatitis type 1 or cryptogenic hepatitis patients. [5]
Alpha-actinin-2 is a 103.8 kDa protein composed of 894 amino acids. [6] [7] Each molecule is rod-shaped (35 nm in length) and it homodimerizes in an anti-parallel fashion.. Each monomer has an N-terminal actin-binding region composed of two calponin homology domains, two C-terminal EF hand domains, and four tandem spectrin-like repeats form the rod domain in the central region of the molecule.
The antibody with the higher affinity for a specific epitope will surpass antibodies with a lower affinity for the same epitope. [ 2 ] [ 3 ] By conjugating the antibody to a fluorophore , the position of the target biomolecule is visualized by exciting the fluorophore and measuring the emission of light in a specific predefined wavelength using ...
Smooth muscle alpha-actin is the predominant isoform within smooth muscle. There is also a lot of actin (mainly beta-actin ) that does not take part in contraction, but that polymerizes just below the plasma membrane in the presence of a contractile stimulant and may thereby assist in mechanical tension. [ 8 ]
Actin, gamma-enteric smooth muscle is a protein that in humans is encoded by the ACTG2 gene. [5] [6] [7] Actins are highly conserved proteins that are involved in various types of cell motility, and maintenance of the cytoskeleton. In vertebrates, three main groups of actin isoforms, alpha, beta and gamma have been identified.
Actin is a family of globular multi-functional proteins that form microfilaments in the cytoskeleton, and the thin filaments in muscle fibrils.It is found in essentially all eukaryotic cells, where it may be present at a concentration of over 100 μM; its mass is roughly 42 kDa, with a diameter of 4 to 7 nm.
